Title: Improvements to precast unit building construction
IPC: E04B2/04
Filed: 1943-03-23
Abstract: 571,659. Building units. STIRLING, E. M. March 23, 1943, No: 4733. [Classes 20 (iv) and 87 (i)] A building unit comprises a wall or like forming portion and an integral pier formation, said formation including a part of reduced depth and lateral extensions on one or both sides of the unit adjacent such part, the formation being adapted to inter-engage with complementary pier formations on like units with the parts of reduced depth lying one above the other. In the construction shown in plan in Fig. 2, and disassembled in Fig. 4, three wall units 1, 5, 10 of a silo meet at angles of 120‹. The lowermost unit 1 has a pier element 4 and a notch 2, the notch serving to receive the neck 8 which joins the unit 5 with its pier element 9. The recess 7 beneath the neck 8 fits over the neck 3 of unit 1, and a recess 6 above neck 8 receives the neck 12 of the uppermost unit 10 which is integral with a pier portion 13. When the units are assembled the various pier portions between them close the gaps between the corners of the units, see Fig 2, and a complete pier at the junction of the units is thereby formed as the successive courses are laid. The units have grooves 15 and tongues 14 which inter-engage with those of the adjacent courses, cement grouting being placed in the grooves to complete the joint. Holes 17 are provided in the pier elements for receiving reinforcing rods which, when in position are grouted in. In Figs 5 to 8 (not shown), modified 'forms of units are described for use when (a) two units only meet at 120‹, (b) two units are connected in alignment, (c) two units in alignment and a third at right angles to them meet at a point, (d) two units meet at 90‹ and (e) four units meet at a point. Alternative applications of the units include their use as floor beams wherein the inlocking pier portions form the head section of a pier or column, and as stays or ties between the columns of a water tower.

Abstract: 1,028,652. Furnace walls. PILKINGTON BROS. Ltd. Feb. 7, 1963 [Feb. 7, 1962], No. 4749/62. Heading F4B. A furnace has side walls formed individually of heat-reflecting partitions mounted in spaced relationship, said spaced relationship being maintained by heat-insulating material and said partitions being held together as a unitary structure. A furnace for heating sheets of glass to be toughened has side walls 1 of which at least one is removable comprising heat-reflecting portions 2, 3, 4, 5, 6 and 7 spaced at 1 to 2 inch intervals in a rigid frame 9, containing heat insulating refractory material 8, at their lower ends and similarly in a frame 10 at their upper ends. The frame 9 is mounted on a refractory foundation 15 and has a refractory roof 16, the aperture 17 of which is closed by pneumatically-operated sliding members 18. The foundation is protected by a replaceable tile 20. The partition 2 extends inwardly to the vicinity of the aperture 17 and supports by means of refractory bodies the electric heating elements of nickel-chrome strip. The furnace may alternatively be heated by the injection of hot air or combustion gases. In a modification of the invention, Fig. 3 (not shown), the material to be treated is transported through the furnace by a vehicle on rails, end walls with spaced partitions being movable to close the end openings. The partitions are spaced by an insulating, refractory material and they may be corrugated to increase their rigidity.

Title: Improvements relating to a method of and apparatus for producing low pressure steam
Inventor: BURROWS RICHARD
IPC: F22B1/08

Abstract: 1,049,831. Heating steam boilers by steam or hot water. JOHN THOMPSON WATER TUBE BOILERS Ltd. Feb. 10, 1964 [Feb. 15, 1963], No. 4873/63. Heading F4A. In power station boiler plant operating at steam pressures of from 1600 to 3500 p.s.i., low pressure superheated steam for soot blowing, fuel oil heating and atomizing, steam pipe tracing and other purposes is generated by H.P. saturated steam or high pressure, high temperature water extracted from the boiler by feeding the steam or water successively through superheating and steam generating tubes of a L.P. steam generator and returning the condensed steam or lower temperature water to the H.P. steam generator. The L.P. generator, Fig. 1 (not shown), consists of a horizontal, cylindrical vessel 1 having water heating coils 2 disposed in its lower part, the coils being connected between headers 4, 5. The vessel 1 is surmounted by a steam dome 6 containing a bank of superheating coils 8. High pressure steam enters the coils 8 at 9 and is condensed therein, the condensate flowing through a line 10 to the header 4 and successively through the coils 2, the header 5, coils 15 in a drains cooler 11 and a control valve 20 to pass to the main turbine feed heating train of the H.P. boiler. Feedwater Which may be impure, for the L.P. boiler is preheated in the cooler 11 and flows into the vessel 1 at a rate to maintain a level 23 therein. The water is evaporated by the coils 2, the steam being superheated in the dome 6 and discharging through an outlet 7. The setting of, the condensate outlet valve 20 is controlled by the steam pressure in the vessel 1 as sensed at 22 to maintain a flow through the coils 2 such that the pressure of the L.P. steam remains constant. In a modification, Fig. 2 (not shown) H.P. water is fed to the L.P. generator from the outlet of the circulating pump of a forced recirculation H.P. boiler, the water at a lower temperature returning to the H.P. steam and water drum.

Title: An improved process for the methylation of aromatic amines
IPC: C07C209/68
Filed: 1940-03-18
Abstract: 539,747. Methylation of aromatic amines. BURAWOY, A. March 18, 1940, No. 5024. [Class 2 (iii)] A process for the methylation of aromatic amines in which the p-position to the amino group is free comprises heating to a temperature exceeding 300‹ C. the corresponding anhydro-amino-aryl alcohols of the general formula (R-N=Ar=CH 2 ) n  where Ar is an aromatic nucleus, R is hydrogen or an aliphatic or aromatic radical. The preferred temperature is between 400‹-500‹ C. The yield of methylated amine is generally improved by effecting the heating in the presence of an alkaline substance such as the hydroxide, oxide, carbonate, bicarbonate, acetate or borate of the alkali and alkaline earth metals and magnesium. The re-actionmay also be carried out by heating the material in a closed vessel under pressure. The anhydro-amino benzyl alcohols may be isolated before the heating or they may be prepared and the re-action products heated without isolating the compound. The compound which is known as isomer anhydroformaldehyde aniline and which is obtained by heating anhydro-formaldehyde aniline with glacial acetic acid may also be used as a parent material for the present invention. The anhydro-amino-aryl alcohols may be prepared by : (1) Treating anhydro-formaldehyde aniline or its homologues prepared by condensation of the amine and formaldehyde in neutral medium with mineral acid. (2) De-hydrating p-amino aryl alcohols of the general formula R-NH-Ar- CH  2 .OH, or deaminating p-amino-arylamines of the general formula R.NH-Ar-CH 2 .NR 1 R 2 . A number of examples are given of the heat treatment of various parent materials to give the required methylated amine.

Abstract: Ethyl aocohol is produced by passing a mixture of ethylene and steam over a catalyst comprising phosphoric acid and copper or manganese or a compound of one of these metals decomposable by phosphoric acid, the amount of phosphoric acid being greater than that corresponding with the orthophosphate but not more than 95 per cent of the catalyst.  The catalyst may be used in granules or tablets, and may be supported upon or mixed with inert but not siliceous carriers, which may be impregnated with the catalyst in liquid form and used with or without drying.  If the catalyst is liquid under the conditions of operation, the reaction mixture may be passed through the catalyst.  The process may be effected at 100-300 DEG  C. and at atmospheric pressure or at pressures up to 250 atmospheres.  Examples describe the use of catalysts comprising from MnO,2H3PO4 to MnO,3H3PO4; CuO,2H3PO4; and MnO,CuO,4H3PO4; the catalysts are dried at 200 DEG  C.
